The inspiration of the building block box is based on the splicing, stacking and matching of the building blocks in a variety of shapes. This product is assembled by circular protrusions and grooves, and various parts can be spliced together.

Disassembly and assembly can be operated by itself, which is simple and convenient, not only improves the playability, but also flexible and changeable storage methods.
